It provides peak power of 480 watts. This unit will appeal to mobile DJs, street musicians and solo artists. It is intended for use at outdoor celebrations, beach parties, sports events and whilst travelling. The built-in rechargeable battery should last for up to eight hours, according to the manufacturer. There is a built-in mixer for the processing of various signal sources – USB stick, SD card or Bluetooth for digital as well as XLR/jack (Mic/Line) and RCA/mini-jack (Line). There is also a 16-channel UHF radio receiver operating in the registration-free frequency range from 863 – 865 MHz.

Test report LD Systems Roadbuddy 10. Construction
The unit is roadworthy, the case looks impressive and the rollers function perfectly. The handle can be retracted just as far as on normal rolling luggage, and locked. The LD Systems Roadbuddy 10 can be comfortably pulled behind you, or if need be, carried over short distances, thanks to its reasonable 16.5 g weight.

Connections
The XLR sockets are lockable (so the cables are not pulled out accidentally). The buttons for music operation via USB etc. have a well-defined response. Excellent: Rubber caps are available for the phono and BNC sockets, to prevent long term ingress of dust etc. if these sockets are not used. Only the rotary control knobs could have been a little tighter.

The “glove compartment”
On the top you will find a storage compartment which opens with a gentle push. Here there is space for everything that you may need on the road – the supplied wireless microphone, the Bluetooth remote control, the UHF antenna and the mains cable. Instead of the cable you could also store a second hand transmitter microphone for duets, dialogues etc. Indeed, a second UHF radio receiver can even be installed in the LD Systems Roadbuddy 10.

Mixer section
There are four channels available:

– Radio reception (UHF, ISM band)
– Media player OR (Line via phono/3.5 mm)
– Mic/Line via XLR/6.3 mm
– Mic/Line via XLR/6.3 mm.

After adjusting the channel volumes, a wide ranging 2-band EQ is available to facilitate extensive sound adjustment. The EQ sounds good and is easy to use. In the test I could make all of the source material sound pleasant.

You will also find a rather rudimentary echo effect (delay time etc. cannot be adjusted), and a limiter at the end of the signal chain protects against overloading and damaging the hardware. Finally, there is a line output (large jack, mono) for recording. Altogether, there are plenty of mixing options available for its intended applications. Of course, it is not intended for band use. Incidentally, guitarists or bassists may want to opt for the above-mentioned product variant, LD Systems Roadbuddy 10 LDRBUD10HS, as this comes with a pocket transmitter with high-impedance input.

Playback & players
In addition to the analogue inputs via the above-mentioned sockets, the following inputs for digital sources are also available:

– USB stick (file formats MP3, WMA, WAV)
– SD card (file formats MP3, WMA, WAV)
– Bluetooth-enabled devices (smartphone etc.)

Handy for the playback of your own productions or MP3s, or for sounds on demand during lectures or presentations etc. My USB stick was initially not recognised. After re-formatting to FAT32, it worked and I was able to play the WAV files stored on it without a problem. The multilingual manual does not provide any information on this. It could also be laid-out more clearly by dividing it into separate chapters for each language.

MP3 Player etc.
Audio files from USB, SD card or Bluetooth can be controlled using the built-in player’s controls and display. The section labelled “MP3 PLAYER” is just below the radio receiver slots in the picture. Here you can:

– switch between pieces of music
– play music in a loop
– adjust the volume separately
– select different EQ curves (in addition to the 2-Band EQ on the mixer).

All of this is controllable by the supplied remote control. In addition, the numbered buttons enable selection of a specific track. What more could you want? Perhaps the option to move within a track or to navigate to subfolders on the USB stick or SD card. Personally, I can do without both of these.

Setting up the radio link
Radio signals can be received in the registration-free range from 863 – 865 MHz (UHF radio). Connect the supplied antenna to the LD Systems Roadbuddy 10 and insert the batteries in the supplied radio microphone. Now just turn the rotary knob to switch on the receiver and adjust the volume. Microphone transmission over the ether was immediately successful.

Wireless microphone sound quality
The microphone is a dynamic cardioid type (sound is not picked up from the side or the rear). Thanks to the matt, rubberised grip area it sits nicely in the hand, and at 275 grams it is pleasantly light. With a pair of quality AA batteries it will work for up to 10 hours. The sound quality is good – in conjunction with the portable PA, good speech intelligibility was evident. The microphone responded insusceptibly enough to sibilants and plosives (heavy breaths as in “p” and “b”) for my taste and for this price category. You really have to get up close to it before it starts to get unruly.
